Characterization of N,C-codoped TiO2 films prepared by reactive DC magnetron sputtering

Electrospun nitrogen and carbon co-doped porous TiO2 nanofibers with high visible light photocatalytic activity

“…Codoping nonmetal elements in TiO 2 has been found to be an effective method to overcome the problem. 11 Cong et al synthesized the C-N-TiO 2 nanoparticles by a microemulsion-hydrothermal process and researched their structure and photocatalytic activity. 8 Li et al found that N-F co-doped TiO 2 nanomaterials have a higher visible-light photocatalytic activity than TiO 2 doped solely with nitrogen or fluorine.…”

First‐Principles Calculations on Electronic Structures of N/V‐Doped and N‐V‐Dodoped Anatase TiO2 (101) Surfaces

“…For this purpose, researchers modified TiO 2 by means of multi-ion codoping. Briefly, there are three kinds of codoping, including nonmetal codoping (N-F-codoping, [13][14][15][16] C-S-codoping, [17] N-C-codoping, [18][19][20] C-Cl-codoping [21] ), metal codoping (Ni-Nb/Ta-codoping, [22] Fe-Ta-codoping [23] ), and nonmetal and metal codoping [X(N, C)-TM(W, Re Os)-codoping, [24] N-V-codoping, [25,26] N-The energetic and electronic properties of N/V-doped and N-Vcodoped anatase TiO 2 (101) surfaces are investigated by firstprinciples calculations, with the aim to elucidate the relationship between the electronic structure and the photocatalytic performance of N-V-codoped TiO 2 . Several substitutional and interstitial configurations for the N and/or V impurities in the bulk phase and on the surface are studied, and the relative stability of different doping configurations is compared by the impurity formation energy.…”

Wear resistant multiphase compound of Ti(C, O, N)/a-C:H nano composite film

“…In addition, some pores are deeper up to 10-15 nm in this film as shown in z-scale of the AFM image. Formation of pores is related to oxidation of metallic compounds and radicals which nucleate and form bigger size [18,19]. Therefore, pores are chemically reactive and generally oxidized which is embedded within smaller particles.…”
